Because of their late start (researchers had intended to study mice from early ages but were stymied by technical difficulties), scientists weren't sure they could expect clear results.

To be sure, Urumqi is now a city of skyscrapers, but its population is almost 75% Han Chinese, and the Uighurs claim they're frozen out of jobs - and see themselves as the victims of China's own westward expansion...
